Passage: "Telephone" was written by Lady Gaga, Rodney Jerkins, LaShawn Daniels, Lazonate Franklin and Beyoncé. Musically, the song has been described as dance-pop. Although constructed as a duet, Beyoncé's first appearance is in the middle verse. She sings her lyrics through a brief interlude, and later backs the chorus during the rest of the song. The song starts off unassumingly, with Gaga singing in a solemn voice over a harp melody, which changes immediately to a pounding beat. Essentially, Gaga is in a club and her boyfriend keeps calling, but she cannot talk as she was drinking and dancing to her favorite song. The chorus runs as follows: "Stop calling, stop calling, I don't want to talk anymore." "Telephone" consists of an expanded bridge, verse-rap and an epilogue where a voice announces that the telephone line is not reachable at that moment. According to the sheet music published at Musicnotes.com by Sony/ATV Music Publishing, the song is set in the time signature of common time, with a tempo of 122 beats per minute. Gaga's vocals range from the low-note of F to the high-note of C. It is set in the key of F Dorian mode, and has a basic sequence of Fm–A–B–Fm as its chord progression.
